Interactive Brokers has launched a new trading feature that brings together multiple US prediction market platforms into one interface, allowing clients to access and trade contracts linked to real-world events without switching between accounts.
According to Thursday’s announcement, the broker is now connecting its clients to Kalshi, CME Group and ForecastEx through one integrated system. The new platform aggregates similar contracts into a single view, enabling users to search, compare and trade across venues in real time.
The automated ordering system scans prices across the three exchanges and routes trades to the venue offering the best net price, including fees. This setup is intended to remove the need for customers to open or fund separate accounts on each platform.
